context_page_description: The Doryctinae or doryctine wasps are a large subfamily of braconid parasitic wasps. Numerous genera and species formerly unknown to science are being described every year. This subfamily is presumably part of a clade containing otherwise any or all of the Alysiinae, Braconinae, Gnamptodontinae, Opiinae and Ypsistocerinae, and might be most closely related to the last one of these. Whether the Rogadinae are also part of this group is not known.
context_section_description: Doryctines have been used to control pests in Europe, Australia, and North America. Several doryctine wasps are of economic importance as biocontrol agents in Australia against eucalyptus pests. The species Spathius agrili has been introduced to the United States from China in an effort to control the Emerald ash borer.
